6 | Carcinogenicity | Category 1B |
Danger |
H350 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1), it was designated in the public announcement on guidelines in order to prevent the impairment of worker's health caused by the chemical substances decided by the Minister of Health, Labour and Welfare based on paragraph (3) of Article 28 of the Industrial Safety and Health Act, and based on (2) and (3), an increase in the incidence of malignant tumors was observed in two animal species, and there is sufficient evidence of carcinogenicity in animal studies, and therefore, it was classified in Category 1B. Also, based on the new information source, the classification result was changed. [Evidence Data] (1) This substance is a substance subject in the public announcement on guidelines in order to prevent the impairment of worker's health caused by the chemical substances decided by the Minister of Health, Labour and Welfare based on paragraph (3) of Article 28 of the Industrial Safety and Health Act (public announcement on guidelines to prevent the impairment of health, No. 23 on October 10, 2012). (2) In a carcinogenicity study by 2-year inhalation exposure with rats (OECD TG 451, GLP: vapor, 25 to 400 ppm), hepatocellular adenoma, hepatocellular carcinoma, hemangiosarcoma of the liver, bronchioloalveolar adenoma of the lung, and trichoepithelioma of the skin/appendage were observed both in males and females, and in addition, adenoma and adenocarcinoma in the large intestine were observed in males, and an increase in the incidence of adenoma in the large intestine was observed in females (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005), IARC 125 (2020)). (3) In a carcinogenicity study by 2-year inhalation exposure with mice (OECD TG 451, GLP: vapor, 25 to 400 ppm), an increase in the incidence of bronchioloalveolar adenoma, bronchioloalveolar carcinoma, and adenosquamous carcinoma and squamous cell carcinoma of the lung, squamous cell papilloma of the forestomach, and adenoma of the Harderian gland was observed in males, and an increase in the incidence of bronchioloalveolar adenoma, bronchioloalveolar carcinoma, squamous cell papilloma and squamous cell carcinoma of the forestomach, and adenoma of the Harderian gland was observed in females (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005), IARC 125 (2020)). (4) There is suggestive evidence that this substance induces inflammation and accelerates cell proliferation, and there is suggestive evidence that this substance is genotoxic (refer to the Reference Data), both of which are strong evidence in experimental systems that the substance has key characteristics of carcinogen (IARC 125 (2020)). [Reference Data, etc.] (5) As for the classification results by domestic and international organizations, the IARC classified this substance in Group 2B (IARC 125 (2020)), the Japan Society For Occupational Health (JSOH) classified it in Group 2B (Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2021)). |

7 | Reproductive toxicity | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. Besides, (1) was not used for the classification because it lacked clear dose relationship, and there was no statistically significant difference. [Reference Data, etc.] (1) In a reproduction/developmental toxicity screening test with rats dosed by gavage (OECD TG421, GLP: 4 to 100 mg/kg/day, males: a total of 42 days including 14 days before mating to the mating period, females: 40 to 51 days from 14 days before mating to day 3 of lactation), no significant effects due to administration were observed in male or female parent animals except that an increase in liver weight and centrilobular hepatocellular hypertrophy were observed at the high dose (100 mg/kg/day). However, during the lactation period, insufficient nursing behavior was shown in 2 dams (2/12) at 20 mg/kg/day and in 1 dam (1/12) at 100 mg/kg/day, and all liveborn pups died. As a result, the viability indices on postnatal day 4 for liveborn pups were 96.8, 94.8, 75.5, and 72.0% in the control group, the 4 mg/kg/day dose group, the 20 mg/kg/day dose group, and the 100 mg/kg/day dose group, respectively, and a tendency of a decrease (without significant difference) in the viability index on postnatal day 4 was observed at or above 20 mg/kg/day. By individuals, in a mid-dose or higher group, even in some dams other than the above 3 cases, the viability index on postnatal day 4 in liveborn pups was considerably below the lower limit (83.3%) of the control group, and the group average was also below the range of the background data of the testing laboratory from 2005 to 2010 (81.8 to 100%). The authors stated that, although there is no dose relationship, it could not be denied that a decrease in nursing behavior in a 20 mg/kg/day or above dose group and a tendency of a decrease in the viability index on postnatal day 4 in liveborn pups were due to the administration of the test substance and reported that the NOAEL of reproductive and developmental toxicity was 4 mg/kg/day (Toxicity Testing Results for Existing Chemical Substances under the Chemical Substances Control Law (2010)). |

Warning |
H336 | P304+P340 P403+P233 P261 P271 P312 P405 P501 |
[Rationale for the Classification] Based on (1) to (4), it was classified in Category 3 (narcotic effects). Also, based on the new findings, the classification result was changed. [Evidence Data] (1) It was reported that, in an acute oral toxicity test with rats (OECD TG 401, GLP), salivation was observed at 500 mg/kg (males, within the range for Category 2) and 800 mg/kg (females, within the range for Category 2), incomplete eyelid was observed at 1,300 mg/kg (within the range for Category 2), and a decrease in locomotor activity, prone position, incomplete eyelid, eyelid closure, ataxic gait, salivation, etc. were observed at 2,000 mg/kg (within the range for Category 2). Also, the LD50 was 1,300 to 2,000 mg/kg (males) and 800 to 1,300 mg/kg (females) (Toxicity Testing Results for Existing Chemical Substances under the Chemical Substances Control Law (2000)). (2) It was reported that, in an acute oral toxicity test with rats (GLP), gait abnormalities, lethargy, and a decrease in respiratory rate were observed; abnormal posture, paleness of the limbs, and ptosis were observed at 800 mg/kg (within the range for Category 2); and swelling of the membrane of the inner corner of the eye (4/5 animals (males), 1/5 animals (females)), and tremor (1/5 animals (females)) were observed at 1,000 mg/kg (within the range for Category 2) (REACH registration dossier (Accessed Nov. 2021)). (3) It was reported that, in an acute oral toxicity test with rats, depression, and hypoactivity were observed. Also, the LD50 was 930 mg/kg (males) and 1,100 mg/kg (females) (REACH registration dossier (Accessed November 2021)). (4) It was reported that, in an acute inhalation exposure test with rats (vapor, 4 hours), congestion and irritation of the trachea mucosa, and edema and swelling of the nerve tissues of the brain were observed; visceral congestion and hemorrhage in the lung were observed as necropsy findings; and fatty degeneration of the liver and albumin-like degeneration of the kidney were observed as histopathological findings. Also, the LC50 was 6.5 mg/L (1,009 ppm (males)) and 7.27 mg/L (1,129 ppm (females)) (REACH registration dossier (Accessed Nov. 2021)). |

H372 H373 |
P260 P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) to (4), effects on the respiratory organs and liver were observed, and therefore, it was classified in Category 1 (respiratory organs), and Category 2 (liver). In addition, the effects on the kidney observed in (3) were considered to be age-related symptoms, and therefore, the kidney was not adopted as the target organ. The classification results were changed based on the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) It was reported that, in a repeated dose 28-day oral toxicity study with rats dosed by gavage (OECD TG 407, GLP), salivation, increases in absolute and relative liver weight, centrilobular hepatocellular hypertrophy, a decrease in Ht (males), an increase in mean corpuscular hemoglobin concentration (males), increases in absolute and relative kidney weight (males), atrophy of the seminiferous tubules (males), hyperplasia of the forestomach mucosa (males), and an increase in serum chlorine concentration (females) were observed at 100 mg/kg/day (converted guidance value: 31.1 mg/kg/day, within the range for Category 2) (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2000)). (2) It was reported that, in a repeated dose 13-week subchronic inhalation toxicity study with rats (OECD TG 413, GLP, vapor, 6 hours/day, 5 days/week), goblet cell proliferation of the nasopharynx (moderate to slight), an increase in liver weight (males), and goblet cell proliferation of the nasal cavity (slight) (males) were observed at 0.322 mg/L (converted guidance value: 0.23 mg/L, within the range for Category 2); an increase in liver weight (females) and goblet cell proliferation of the nasal cavity (slight) (females) were observed at 0.644 mg/L (0.46 mg/L, within the range for Category 2); and an increase in kidney weight, hyperplasia of the respiratory epithelium, and an increase in heart weight (females) were observed at 1.288 mg/L (0.92 mg/L, within the range for Category 2) (Results from preliminary Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2002). (3) It was reported that, in a repeated dose 104-week inhalation toxicity study with rats (OECD TG 451, GLP, vapor, 6 hours/day, 5 days/week), inflammation of the respiratory epithelium (males) and an increase in the incidence of chronic nephropathy (females) were observed at 0.161 mg/L (converted guidance value: 0.115 mg/L, within the range for Category 1); and an increase in liver weight, an increase in kidney weight, a tendency of an increase in the number of severe cases of chronic nephropathy, an increase in urea nitrogen, bile duct proliferation, and respiratory epithelial metaplasia of the nasal gland (females) were observed at 0.644 mg/L (0.46 mg/L, within the range for Category 2) (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005)). (4) It was reported that, in a repeated dose 104-week inhalation toxicity study with mice (OECD TG 451, GLP, vapor, 6 hours/day, 5 days/week), an increase in bronchioloalveolar epithelium proliferation was observed at 0.161 mg/L (converted guidance value: 0.115 mg/L, within the range for Category 1), and an increase in the incidence of squamous hyperplasia of the forestomach (females), an increase in the incidence of eosinophilic alterations of the nasopharynx epithelium (females), and a decrease in platelet count (females) were observed at 0.644 mg/L (0.46 mg/L, within the range for Category 2) (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005)). |
